SYSTEM OF VALVES RELATING 'IO INTERNAL-COMBUSTION ENGINES.

Application filed February 9, 1927'. Serial No. 166,821.

This invention relates to improvements in the system of valves for ii'l'ternal combustion engines, or motors, and has for its object to proviijle a construction of combined elements that as to the results produced, in several ways will. prove SUPOllOl' to those hitherto known, and employed.

Among the :alvantages oi? this construction is thus the attaclnnent of this valve systeiu to the side ot the cyliiuler, whereby said valve or valves are under no influence of the change oi temperature in case Where the valve system is located. in more intimate contact with the combustion chaniiber, and I have thus eliminated the possibility of any buckling or warping of said valve with attending irregulinity of motion.

Another object of my invention is to simplify the construction of a motor by eliminating a number of movements, and at the same time increase the WOl'kliig power of said engine, and the dependability and eliiciency of same.

A further object oi? my invention is to pro dure a specimen oi? valve that may be easily re ilaced, or repaired, and whichon account oft its simplicity of construction, combination and design will prove very exact in operation, create a. pertectly noiseless engine, and at the same time be very inexpensive to manu'iiarc: ture, as I employ a smaller number 01 parts than found in other motors 01 this type.

It is further to be pointed out as an advantage that on account of the relatively large sliding surfaces of the valves exposed to wear, said Wear and tear will naturally be e msiderably reduced and in inverse proportion to that oil' a poppet valve with its much smaller surface. This accordingly will admit the possibility of employing to a great extent a lighter, durahle metal throughout the motor, which would practically make this motor, or engine, one of lightest build, and one especially suitable to be installed in automobiles as well as aeroplanes. I

The water-cooling system has been provided with a larger 'contactsuriiace than usually, and this has been so arranged as to equalize the temperature relative to the surroundings of said engine.

lt hilel have shown and describedmy con-.

struction to embrace two valves suitable for inotive-power engines of the reciprocatory type, and likewise shown and described a single valve for said purpose, I do consider the nor.

claimed, and illustrated in the accompanying drawings l'ormiijig parts of this specification, and in which similar characters oi reference indicate corresponding parts in all views and in which Figure 1. is a vertical sectional view taken on line 7)-7) of Fig. 2, illustrating an embodiment of my invention; Fig. 2 is a longitudimil sectional view taken on line a e of jliig. 1; Figs. 3 and 4 are detail views in section Fig. 5 is a similar view oi the maniliold, \vhile Fi g. 6 is an illustration, in part, of actuating means, that nmybe applied to mydevicc.

li-eterring more particularly, to the drawings 11 indicates a cylinder of an internal com. ustion engine of the tour cycle type equipped with the improved valve mechanism; 12 indicates a water jacket, and 13 an explosion chamber inclosed in the cylindeu blocln -13 indicates the partition wall between the intake and outlet in the .n'iani'liold.

The igniter is shown at 14-, and the piston 15 1s ]()]Il0(l by a connecting rod 16 to the crank shaft 17. The cylindrical block-head may be made integralwith said blocl; or may be de v i tachably secured to the same.

The single valve 28 illustrated in Figure 1 is groovedinto the cylinder-block, as shown at 42 in Figure 2, in a dovetailed manner and enclosed. by a casing 27, which is made in tegral, with the exhaust 20and the int-alto 21; said casing is secured to the head by means of bolts as at 25, and to the base of the cylinder-block by means of screw-bolts, as

C at .26 a suitable packing is used to secure aforesaid. parts together in a compact man- The con'ibination, as described, of the exhaust and manifold naturallysnuplilies the feature of an engine, and incidentally has the advantage of heating the gas supply before this enters the engine. The single valve system, as illustrated, comprises a flat, rectangular shaped plate of sufficient thickness mounted in a lateral position, and at an acute angle to the cylinder-block, as shown in Fig. 1. A luln'icating systeni not shown) is attached to the middle of the valve casing for lubricatin said valves.

It is evident that the carbon produced incidental to the operation of the engine, as constructed, will add to the lubrication of the valve plates bringing about a higher compactness and thereby increasing the compres- It will be seen that the position of the valve at an acute angle to the block admits of a straight pull on the former, a feature ofv very great importance, and specifically claimed, being contrary to the usual manner "of pulling away from the center. i

The important difference between the single valve-system and the generally used double-valve system, hes in the quicker action produced on account of the specially con- 'latter is in turn mounted upon a cam-shaft operated by means of a gear mechanism.

I have in Fig. 6 illustrated another manner of operating said single valve, that is by using the bell crank principle, as indicated at 35, which has its fulcrum at 36, making it possible in this case to use a smaller cam; and also multiplying the stroke by employing a proportionately longer lever 37.

While the function of theengine in respect to the valve is well known and understood, I have in Figs. 3 and 4 illustrated different positions of said valve according to the stage of operation, thus in Fig. 3 said valve has attained its middle position, while at Fig. 4: it is shown in a downward position.

The intake and exhaust ports of said valve are indicated at 38 and 39 respectively, and the communication to the cylinder-block is shown at 4:0, in dotted. lines. 7

It is obvious that changes may be made inthe form, construction and arrangement of the several parts, as shown, within the scope of' the appended claims, without departing from the spirit of the invention, and I do not therefore limit myself to the construction and arrangement shown and described herein. a I
